When Katja "Kat" Lombardo wakes up near the dead body of her partner with a gun in her hand and no memory of what happened, she calls on the only person she trusts to help her-Zak Delaney, the lover she abandoned two years ago. Now Zak must put aside his anger toward Kat in order to find the real killers before he once again loses the woman he loves...this time for good.
